IPC: C07C49/84
Filed: 1990-03-13
Abstract: PURPOSE:To obtain ketones corresponding to two molecules of raw materials of carboxylic acids having alpha-hydrogen in at least one molecule by decarbonate condensation reaction in high yield with using an oxide containing chromium and zirconium as a catalyst. CONSTITUTION:Ketones useful as intermediates of organic synthesis are produced from two molecules of carboxylic acid compound or derivative of said compound by decarbonate condensation reaction in vapor-phase catalytic reaction. In the process, said reaction is accelerated by using a compound having at least one hydrogen atom on carbon of alpha-position to carboxylic group as at least one molecule in said raw materials and simultaneously suppressing separating out of carbonaceous material by using an oxide containing chromium and zirconium preferably in an atomic ratio of about Zr:Cr=1:0.005-0.10 as a catalyst to afford the aimed compound in high yield with a long catalyst life. Besides, carbonaceous material attached to the catalyst is able to be burned and removed to recover in a modest condition.

Title: Throttle machine
Inventor: OKADA KAZUO
IPC: G07F17/34
Filed: 1983-04-08
Abstract: A slot machine is provided which has a winning probability table for storing a relation between a group and random numbers, the group being one of a plurality of groups made up by classifying winning-prize symbol combinations. The range of random numbers is properly fixed so that the winning probability is determined. Prior to the start of a game, one of the random numbers is sampled out from a plurality of random numbers. The decisions on whether there is a win or not, and on which group the sampled random number belongs to if there is a win, are made with reference to the winning probability table. A hit request signal is generated for the latter decision. The series of symbols in movement is controlled in accordance with the hit request signal.

Inventor: OZAKI TAKAYUKI
IPC: H04L9/10
Filed: 1983-04-08
Abstract: PURPOSE:To obtain a time-division ciphering system which ciphers a plain sentence and deciphers a ciphered sentence by one arithmetic part by shifting either of a transmit and a receive clock in phase and controlling a control part by the transmit clock and a phase-shifted receive clock alternately. CONSTITUTION:The ciphered sentence modulated by the frequency of transmission from an opponent station A is demodulated into a code by a DCE3 and this code is inputted to an input register 15 through an input/output part II. An input register 15, CONT11' and output register 16 are controlled by a clock 17' obtained by inverting the receive clock 17 by an inverter 21. The ciphered sentence outputted by the input register 15 is selected by an SEL 19 under the control of the CONT11' and inputted to the arithmetic part 13'. The arithmetic part 13' deciphers the input into the plain sentence under the control of the CONT11' by the same key K as the former case, selects it by an SEL20, and outputs the selected sentence from an input/output part 8 to a CPU1 through an output register 16. Thus, ciphering and deciphering are carried out alternately by controlling the CONT11' by the transmit and receive clocks alternately.

Abstract: PURPOSE:To perform supervision independently of the shape of a supervisory object, environments of a supervisory area, or the like by comparing a picked-up image of the supervisory area with a reference image of the same area and extracting difference information between both images to discriminate the existence of a foreign matter in the supervisory area. CONSTITUTION:The image of the supervisory area picked up as the reference image by a camera 1 is stored in an image memory 2 and is subjected to preprocessing and is stored in a reference image memory 3. When supervision is started, the image of the supervisory area is momentarily picked up by the camera 1 and is inputted as a comparison image to the memory 2 and is subjected to preprocessing and is sent to an image comparing part 4. The comparing part 4 compares the comparison image with the reference image to obtain a differential image and transfers it to an abnormality discriminating part 5. The discriminating part 5 discriminates the existence of a foreign matter in the supervisory area in accordance with the inputted differential image. When the existence of a foreign matter in the supervisory area is discriminated by the discriminating part 5, a warning is given by a warning generating part 6.

Abstract: PURPOSE:To eliminate a need of an air conditioner of a weight material by providing an exhaust fan in the vicinity of a blow-off port of a duct and arranging a shutter, which is opened by the wind pressure of the exhaust fan, in the vicinity of the blow-off port of exhaust air of a display device main body. CONSTITUTION:When the operation of an exhaust fan 11 is started, outside air is introduced from an outside air intake 7 through a filter 10 and is led to a duct 5 to cool a light emitting display part 2. The air which cools this display part 2 is discharged to the outside from an exhaust air blow-off port 8 by the exhaust fan 11. In this case, a shutter 12 blows off internal air by the wind pressure of the exhaust fan 11. When the operation of a display device main body 1 is released and heat generation of the light emitting display part 2 is stopped thereafter, the exhaust fan 11 is stopped, and the shutter 1 is automatically closed by the weight of its blade to shut out a cloud of sand or rain drops from the outside. Thus, the air conditioner of a weight material is unnecessary.
